Mastering AutoCAD 2009 and AutoCAD LT 2009
Author: George Omura
Mastering AutoCAD teaches AutoCAD essentials using concise explanations, focused examples, step-by-step instructions, and hands-on projects for both AutoCAD and AutoCAD LT. This detailed resource works as both a tutorial and stand-alone reference. Part I introduces the basics of the interface and drafting tools; Part II moves into such intermediate skills as effectively using hatches, fields, and tables; Part III details such advanced skills as attributes, dynamic blocks, drawing curves and solid fills; Part IV explores 3D modeling and imaging; and Part V discusses customization and integration. The supporting web site includes all the project files necessary for the tutorials and five chapters of advanced material on such topics as Active X and VBA.
